UFO seen in Casey Illinois in 1966

Summary

In October 1966, a witness in Casey, Illinois, observed a bright blue-white object moving across the sky. The object appeared to travel at the same speed as a jet aircraft and made unusual turns: first to the left and then to the right. Despite the clear sky and no sound heard, the witness noted that the object had a side-to-side wavy motion. The observation lasted three minutes and was recorded as part of Project 10073.

The official conclusion was that the object could be a satellite, specifically Echo II, which was passing over the area at that time. Although the witness did not identify it as such, the described characteristics align with those of a visible satellite. This case is an example of how UFO sightings are often explained by known natural or technological phenomena, though they leave open questions for the observers.
